ATTO EYS 9- 'A. J. STOUGES SLUG CASTING MACHINE Original Filed June 19,1951 2 Sheets-Sheet 2 The rod (3 is mounted in fixed bearings D D and isprovided between said bearings with a rigid block or collar and the barM, located to the left of the collar C is formed with an elongated slotm through which the rod C extends. The side face of the bar M opposed tothe bearing D is straight or vertical, while the other face, thatopposed to the block 0*, is inclined upwardly to accord with thesimilarly inclined face of said block. As shown in Fig. 3, the block Cis held resiliently engaged with the bar M by a compression spring. Cseated in the bearing D and serving also to hold the bar; against thebearing D The jaw C moreover, is provided with a compression spring Cmounted in a block D secured to the vise frame D, and which holds thejaw resiliently against the rod C As the parts are thus arranged, whenthe bar M is raised, the rod C and jaw C are forced positively therebyto the right or toward the opposing jaw C whereas when the bar islowered, the rod C and jaw C are forced to the left or returned to theiroriginal positions by their. respective springs C and C The bar M isoperated from the cam shaft R by means of afore-and-aft lever M which isconnected to the lower end of the bar by an intermediate link M Theupward movement of the bar M (in the present instance a positive one),is limited by a stop screw m which is arranged inthe vertical path ofthe lever M and hence the jaw C is always moved a definite distance bythe bar M so as to locate the end matrices of a properly composed linepositioned between the two clamping jaws in registry with the end wallsof the mold slot.

If the line is of proper length, the movement of the left-hand jaw Cwill be imparted by the line to the right-hand jaw G which, under suchcircumstances, is adapted to yield toward the right against the tensionof a spring C which normally holds it toward the left against a fixedstop D and which offers the resistance required for the lock-up of theline. The spring C is supported on a horizontal rod D rigidly mounted ina bracket D fastened to the vise frame D. In yielding, the jaw C isadapted to actuate the safety pump stop lever N common to the commerciallinotype machines, and which, when actuated, permits the cycle ofoperation to proceed, the active mold being moved up against the matrixline and the pot plungers E being allowed to descend by action of thespring E hereinbefore mentioned. If the pump stop lever N is notactuated by the yielding of the jaw C the casting operation can not takeplace.

Although it is believed the operation of the mechanism will be readilyunderstood from the foreging description, it might be here stated thatthe line of matrices being hand composed, is justified in the stick orholder, and delivered in such condition by the transporter B between theclamping jaws C C which normally are spaced apart a distance somewhatlarger than the length of the line for this purpose. The left hand jawis then actuated toward the right hand jaw to lock up the line forcasting, the necessary clamping pressure being furnished by the yieldingright hand jaw C as motion is imparted to it by the left hand jaw 0through the intervening line as it is moved to place the inner faces ofthe end blank matrices in registry with the mold slot.

Having thus described my invention, what I claim is:

1. In a slug casting machine, adapted to be equipped with anon-expansible composed matrix line of a given length, the combinationof a supporting frame, right and left hand clamping jaws mounted forhorizontal movement in said frame, a transporter for positioning saidmatrix line between said jaws, positive means for moving the left handjaw toward the opposing jaw from a normal to a definite predeterminedposition, said means having a range of movement sufficient to reduce thedistance between the jaws to less than the length of said matrix line, aline-clamping spring arranged behind the right hand jaw to permit it toyield under the thrust of the left hand jaw through the composed matrixline, and a fixed stop to limit the yielding movement of the right handjaw.

2. A combination as in claim 1, including a spring for returning theleft hand jaw to its normal position, and characterized by the fact thatthe spring associated with the right hand jaw offers the sole resistancerequired for the justification of the line.

3. In a slug casting machine, the combination of a supporting frame,right and left hand clamping jaws mounted for horizontal movement insaid frame, a transporter for positioning composed matrix lines of agiven length between said jaws, a vertically reciprocatory wedge baradapted in its upward movement to shift the left hand jaw to activeposition against the line, means for operating the wedge bar, and afixed stop for limiting the upward movement of saidbar so as" supportingframe, right and left hand clamping jaws mounted in said frame andnormally spaced apart for a distance corresponding approximately to thelength of said matrix line, means for moving one of the jaws toward theother and having a range of movement sufiicient to reduce the distancebetween the jaws to less than the length of said matrix line, atransporter for positioning the matrix line between said jaws, and alineclamping spring for moving one of said jaws against the line toexert a clamping pressure thereon.

6. In a slug casting machine, adapted to be equipped with anon-expansible composed matrix line of a given length, the combinationof a supporting frame, right and left hand clamping jaws mounted in saidframe and normally spaced apart for a distance correspondingapproximately to the length of said matrix line, a transporter forpositioning the matrix line between said jaws, means for moving one ofthe jaws toward the other and having a range of movement sufficient toreduce the distance between the'jaws to less than the length of saidmatrix line, a line-clamping spring for moving one of said jaws againstthe line to exert a clamping pressure thereon, and means comprising afixed stop for limiting the movement of said jaw to position the line inpredetermined relation with the mold.

'7. In a slug casting machine, the combination of a supporting frame,right and left hand clamping jaws mounted in said frame and spaced aparta predetermined distance to receive lines of a given length, atransporter for positioning composed matrix lines approximately of suchlength between said jaws, a vertically reciprocable wedge bar adapted inits upward movement to shift one of said jaws to exert clamping pressureagainst the line, means for operating the wedge bar, and a fixed stopfor limiting the upward movement of said bar to fix the active positionof said jaw so as to position the line in predetermined relation withthe mold.

8. In a slug casting machine, the combination of a supporting frame,right and left hand clamping jaws mounted for horizontal movement insaid frame, a transporter for positioning composed matrix lines of agiven length between said jaws, a vertically reciprocatory wedge baradapted in its upward movement to shift the left hand jaw to activeposition against the line, means for operating the wedge bar, a fixedstop for limiting the upward movement of said bar so as to locate theleft hand jaw definitely in its active position, said right hand jawbeing adapted to yield under the thrust of the left hand jaw through thecomposed matrix line, and a pump stop device actuated by the yieldingmovement of the right hand jaw.

9. In a slug casting machine, adapted to be equipped with anon-expansible composed matrix line of a given length, the combinationof a supporting frame, right and, left-hand clamping jaws mounted insaid frame and normally spaced 5 apart for a distance correspondingapproximately to the length of said matrix line, both jaws normallyoccupying a position to the left of their active positions, means formoving the left-hand jaw toward the right to its active position and 10through the composed line for moving the righthand jaw toward the rightto its active position, said means having a range of movement sufiicientto reduce the distance between the jaws to less than the length of saidmatrix line, and 5 a line-clamping spring arranged behind the righthandjaw and resisting but permitting its rightward movement; whereby duringcasting the jaws are properly positioned and the composed line clampedunder pressure between them.

10. A combination as in claim 9, characterized by the fact that themeans for moving the lefthand jaw act only to move it toward the rightand include a spring for restoring the jaw to its normal position to theleft after casting. 25
